HMX Cosmic Purple Linear Switches

The HMX Cosmic Purple Linear switch is a smooth, linear mechanical switch designed for users who prefer a consistent keystroke without tactile bumps. It suits typists and gamers looking for a higher-pitched, clacky sound rather than a deep thock. Its unique full POM housing and LY stem produce a vibrant and full sound profile with a slight audible scratch, which may appeal to those who enjoy more pronounced switch acoustics.

Feel & Sound

• Linear and smooth keystroke with no tactile feedback.
• Produces a higher-pitched, clacky sound rather than the typical deep thock of most POM housing switches.
• Full POM housing widens the sound spectrum, making it sound vibrant and full-bodied.
• Includes a subtle audible scratch, which may be noticeable and is a matter of personal preference.

Actuation Characteristics

• Moderate operating force provides a balanced typing experience without requiring excessive pressure.
• Pre-travel and total travel distances support quick and responsive key presses.
• Bottom-out feel is consistent with linear switches, offering smooth keypresses without harsh impact.

Build Quality

• Full POM top and bottom housing enhances sound quality and durability.
• LY stem material contributes to smoothness and sound characteristics.
• Uses a KOS single-stage extended spring for consistent force.
• Factory lubed with a thin coat of 205g0 on stem legs and sliders, plus dry film on spring and leaf, reducing lube pooling issues (lube pooling can cause inconsistent feel).

Trade-offs

• The audible scratch may be undesirable for users seeking a completely smooth and quiet switch.
• Higher-pitched sound may not suit those preferring deeper, thockier acoustics.
• Unknown compatibility details limit assessment for hot-swap or LED use.
